    What is the impact of the steps to Ambient Air Quality?
    Impacts of the steps taken in Delhi: All regulatory pollutants show a decreasing trend in concentrations in Delhi. CO decreased to 3069 µg/m3 in 2000-2001 from 5450 µg/m3 in 1998. NO2 decreased from 75 µg/m3 in 1996 to 59 µg/m3 in 2000. Lead which is harmful especially for children, decreased remarkably due to phasing out of lead from gasoline.

    It is estimated that 75% to 80% of water pollution by volume is caused by domestic sewage.
    The major industries causing water pollution include:
    Distilleries, Sugar, Textile, Electroplating, Pesticides, Pharmaceuticals, Pulp & paper mills, Tanneries, Dyes and dye intermediates, Petro-chemicals, steel plants etc. Non-point sources such as fertilizer and pesticide run-offs in rural areas also cause pollution. Only 60% of chemical fertilizers are utilized in soils and the balance is leached into soil polluting the ground water. Excess phosphate run-off leads to eutrophication in lakes and water bodies.
